I have to say it is the person not the class but Titans by far have cared much longer. Hunters were the ones bouncing off attacks by Titans and warlocks by saying " git gud scrub" or something else. The Titans have done the same thing but they actually care about the people saying "nerf sunbreaker" because they don't want their only class that has a super strong super to go away. You should be able to use a class wether it is bad or not. The only thing I see as not balanced left in the crucible is the DR on sunbreaker. It is too much because it still beats sniper head shots and golden gun (1 shot). That is the only thing that should happen but I truly don't care because everyone that uses a Titan is bad and easy to beat in the crucible.

Hunters obviously Life is good for warlocks
